What is the difference between all of these? Witch one is the best and works the fastest?

If 1 is the best and works fast why are people choosing otherones instead of the best/quickest 1?

Thanks!

Not all of these are anti-biotics. Spiro is for hormonal acne, minocycline is a antibiotic and accutane is Vitamin A deriative. The best is probably Accutane but some people dont see results until they are done with the treatment which can take up to 6 months Accutane is probably the most dangerous med for acne with many side effects but its safe if closely monitored. Everyone response different to different meds. Anti biotics may work with lil or no side effects.
